Traditional masonry construction is the construction method of choice for new homes in England and Wales. The Traditional Housing Bureau states that it is the build method of choice for 70% of house builders.
Supply is driven by demand and in a survey by MORI in 2001, the majority of people surveyed said they would prefer to buy a house of traditional masonry construction. This method is ingrained in our national psyche and most people appear to feel more comfortable putting their faith and money in bricks and mortar.
We'll have a look at masonry construction and the advantages and disadvantages of choosing it as the method of construction for your self build.
Traditional masonry construction refers to houses built in block and brick. Although brick is used countrywide as an outer skin or 'facing material', it is often substituted with local quarried stone or a reconstituted replica.
Despite the use of the term 'traditional', masonry construction has incorporated many modern developments and has come a long way since the days of solid stone walls. Improvements in technical design, materials and accessory products have enhanced the performance of these structures significantly in terms of structural integrity, thermal efficiency and moisture protection. Progress has led to developments such as thin joint systems with Aircrete blocks.
Following excavation and installation of foundations, bricklayers erect cavity walls that consist of an inner and outer skin.
The inner skin is the main structural element, which supports internal floors and the roof structure. It is constructed using concrete blocks laid on beds of sand and cement mortar.
The outer skin is the first line of protection against the elements and provides the aesthetic element to the structure. It is constructed using brick, stone or block work, which can take a number of finishes. The two skins are connected by steel wall ties and separated by a cavity that is partially or fully filled with insulation.
Internal floors can be constructed using timber joists, composite timber I beams, or one of the precast concrete systems available. The roof is usually traditional cut timber or prefabricated truss construction.
Once the roof is completed and the windows and doors are fitted, the building is watertight the internal trades can get underway. The internal face of the blockwork can take a range of finishes including 'dot and dab' plasterboard and wet plaster.
Various details are required around openings and other parts of the structure in order to maintain structural integrity and to prevent water penetration and heat loss.
If you are interested in these and other technical construction details Roy Chudley and Roger Greeno's Building Construction Handbook is a great source of information and drawings.
Let's have a look at some of the pros and cons of masonry construction.
You can get more information on brick and block construction from the Traditional Housing Bureau who promotes the use of brick and block and as always, The Housebuilders Bible 10 is an excellent source of information for all self builders and house builders alike.
As masonry construction is the main method of construction used in the UK it is often the benchmark by which other construction methods are compared in terms of cost, time, quality, performance and sustainability.
Despite a few issues, it still offers some great advantages and attractive characteristics that might fit the requirements of your self build project.
